Abstract
Silkworm (Bombyx mori) is an economically important insect providing more income to farmers. Silkworm pupae also contain proteins and other essential nutrients. Silkworm pupae were used as substrate for cultivating cordyceps which has medicinal properties and benefits in cosmeceutical medicine. From the report, the use of plant hormone such as auxin group can promote the growth of mushroom stalk. Thus, this study aimed to investigate the effectiveness of some plant extracts and hormones on the growth of snowflake cordyceps (Cordyceps tenuipes) by spraying aqueous extract of bean sprouts, aqueous extract of
baby corn and mushroom hormone. Each plant extract and hormone at the amount of 0.5 ml were sprayed on fruiting bodies of snowflake cordyceps cultivated on Khao Dawk Mali 105 rice mixed with silkworm pupae as substrate. The result indicated that aqueous extract of bean sprouts spraying on the cordyceps in day 1, day 4 and day 7 at total amount of 1.5 ml/bottle was the most suitable for promoting the growth of cordyceps. After application, the average height, fresh weight, dry weight and adenosine content of fruiting body were 2.28 cm, 17.23 g/bottle, 1.90 g/bottle and 49.22 mg/100 g, respectively.
